VCSD 6 Sensor Faults Found via ECU (MAF, Oxygen, Mixture, Throttle)
Hi,
Does anyone have any advice on the following diagnostic reading from VCSD? Is this a sign that the ECU is at fault or should I look to replace each part listed below?
Thanks,
Andy

The ECU number shows it is an ADR engine and not an AEB as VCDS has stated, that is the 150 PS 1.8T from the A4/Passat. Clean the throttle body, put the battery on charge, clear the learned values in Adaptation 10 group 000 (do this three times), reset the throttle in basic settings 04 group 098 and make sure the throttle cable is not so tight it is opening the butterfly. Fit a new Bosch or preferably genuine Lambda sensor and run it for a few days to see what comes back. When these engines were more common, I often found that even a genuine Bosch lambda sensor would give the 16514 code as the heater circuit resistance in the sensor would not satisfy the ECU.
